Shading Due to Overhang

The infrared camera can also see the benefit of overhangs in warding off
the sun's heat. While the lower portion of the wall (still in sunlight) is
showing a hot surface, the shaded portion of the wall is noticeably cooler.
This effect will be even more evident on the PVRES house. If you look at
the IR photograph closely, you can see the effect of the window and the corner
that separates the sunlit portion of the wall from the shaded portion. Note
that the two pictures were not taken from the exact same location (the area
within the square is approximately the area shown in the IR camera photograph).

The temperature range is from 94°F (darkest colors) to 103°F (lightest
colors).
